Hi devs,
Short story:
In the new model, does it make sense to support entities that don't have an
unique name to be identified in their 'context'? (so-called 'free name',
as in
free thought).
+1 to force all Entities to have a free form name in the new model
Notes:
* Tthat name could be automatically generated when an object is created. We could use the
format<classname> for the first one and then<classname>2,
...<classname>N - or even<classname>[N] is we want backward compatibility.
* One advantage of always having a name is that there's no problem with removing an
object and thus having a different index or having an index with holes. The object is
always addressable.
* Another advantage is that scripts can be a bit more clean by using a name with a
meaning rather than<className>[N]. For example instead of TagClass[1] it could use
"CommentTags", ie associate a business meaning with a given object.
Indeed for _objects_ there are countless arguments to have names (it's probably
gonna cause quite some mess to maintain, but so does the (current) indexing method).
For entities in general (that is, objects and who knows what else), I'm not that
100% sure, but since I don't see a use case now, and we don't want to refactor,
and we can always workaround (as we'll do for objects for the moment), let's go,
+1
Thanks,
Anca

Long story:
For example, in the current model, an object is an example of entity that does
_not_ have a free name: in a document (its context), an object is identified by
two values: the name of the class of the object and the 'object number'. An
object cannot be differentiated by a single name among all the objects of a
document.
As opposed to this, a document does have a free name to identify it in the list
of documents in a space, namely the page name. The same, an attachment's name is
unique among the attachments of a page, etc.
Note that the discussion is about a human-readable and accessible name for an
entity, for example, using a GUID or other 'identifier' is not an option, since
they are not manipulable by humans (for example to create a reference to such an
entity).
Also note that, even if supporting it is the best solution (which covers all
cases anyway), we want to make sure it's necessary, since it would involve some
refactoring.
Thanks,
Anca
P.S. I haven't made my mind yet.
